After upgrading to openssh-3.6.1p2-1, I get this in my syslog when people log in:
Jun 11 09:12:47 jik sshd[13093]: error: setlogin failed: Function not implemented
The login nevertheless succeeds. Is this a bug or an ignorable informational
message?

The message I reported originally is gone, but this one remains, each time I log
in, with 3.6.1p2-4:
Jul 30 06:44:56 jik sshd(pam_unix)[5302]: authentication failure; logname= uid=0
euid=0 tty=NODEVssh ruser= rhost=jik.kamens.brookline.ma.us user=jik
